TECHNICAL FIELD

Examples set forth in the present disclosure relate to the field ofaugmented reality (AR) devices, including mobile devices and wearabledevices such as eyewear. More particularly, but not by way oflimitation, the present disclosure describes system and methods forcapturing effort put into generating handcrafted AR experiences.

BACKGROUND

Many types of computers and electronic devices available today, such asmobile devices (e.g., smartphones, tablets, and laptops), handhelddevices, and wearable devices (e.g., smart glasses, digital eyewear,headwear, headgear, and head-mounted displays), include a variety ofcameras, sensors, wireless transceivers, input systems, and displays.Graphical user interfaces allow the user to interact with displayedcontent, including virtual objects and graphical elements such as icons,taskbars, list boxes, menus, buttons, and selection control elementslike cursors, pointers, handles, and sliders.

Virtual reality (VR) technology generates a complete virtual environmentincluding realistic images, sometimes presented on a VR headset or otherhead-mounted display. VR experiences allow a user to move through thevirtual environment and interact with virtual objects. AR is a type ofVR technology that combines real objects in a physical environment withvirtual objects and displays the combination to a user. The combineddisplay gives the impression that the virtual objects are authenticallypresent in the environment.

DETAILED DESCRIPTION

The disclosure includes examples for capturing and presenting effort putinto generating a handcrafted AR experience. AR object generation datais captured during the generation of a handcrafted AR object. The ARobject generation data is then processed to generate proof of effortdata for inclusion with the handcrafted AR object. Examples of proof ofeffort data include a time lapse view of the steps taken duringgeneration of the handcrafter AR object and statistics such as totaltime spent, number of images or songs considered for selection, numberof actions implemented, etc. or information tied to such statistics(e.g., a QR code including an address for accessing the statistics).

A lot of effort can be put into interacting with virtual objects in AR.For example, if one makes an AR bear dance, choreographing the danceroutine can require significant effort. Examples in the presentdisclosure display the different effortful AR interactions people engagein. For example, a timelapse is provided that breaks down theinteractions into viewable recordings using, for example, 3D AR replayand metadata of the user’s interactions (time spent, gestures used,etc.). As part of the replay in AR, the user can see the raw andcomplete footage of the process --- with the touchpoint of theinteractions highlighted. For example, while the final output (acustomized AR object) may contain polished version of a dance routine,the timelapse will include all the interactions considered during thedevelopment such as jumps, spins --- some that went into the finalversion and some bloopers.

The handcrafted experiences produce a feeling of digital “handcrafting”in AR to convey meaningful effort. Conventional handcrafted AR systemsfocus on placing AR objects in the world or filters applied to oneselfas opposed to more personalized experiences that can be shared withothers. handcrafted AR experiences or routines are provided through acombination of physical and virtual interactions.

In one example, users can animate and customize a virtual character(e.g., a crocheted bear) in order to generate an AR clip. These clipscan be gifted to other people through physical gestures such as raisingone’s phone or blowing on the phone. This enables users to convey effortby handcrafting the end-to-end routine or experience --- from generatinganimations (such as make the bear jump or perform a dance routine), toscanning real world environment and applying them onto the AR content(such as adding a real flower picture onto the bear’s shirt), tocomposing the scene (through AR drawings and music/voice).

The following detailed description includes systems, methods,techniques, instruction sequences, and computing machine programproducts illustrative of examples set forth in the disclosure. Numerousdetails and examples are included for the purpose of providing athorough understanding of the disclosed subject matter and its relevantteachings. Those skilled in the relevant art, however, may understandhow to apply the relevant teachings without such details. Aspects of thedisclosed subject matter are not limited to the specific devices,systems, and method described because the relevant teachings can beapplied or practice in a variety of ways. The terminology andnomenclature used herein is for the purpose of describing particularaspects only and is not intended to be limiting. In general, well-knowninstruction instances, protocols, structures, and techniques are notnecessarily shown in detail.

The terms “coupled” or “connected” as used herein refer to any logical,optical, physical, or electrical connection, including a link or thelike by which the electrical or magnetic signals produced or supplied byone system element are imparted to another coupled or connected systemelement. Unless described otherwise, coupled or connected elements ordevices are not necessarily directly connected to one another and may beseparated by intermediate components, elements, or communication media,one or more of which may modify, manipulate, or carry the electricalsignals. The term “on” means directly supported by an element orindirectly supported by the element through another element that isintegrated into or supported by the element.

The term “proximal” is used to describe an item or part of an item thatis situated near, adjacent, or next to an object or person; or that iscloser relative to other parts of the item, which may be described as“distal.” For example, the end of an item nearest an object may bereferred to as the proximal end, whereas the generally opposing end maybe referred to as the distal end.

The orientations of the eyewear device, other mobile devices, associatedcomponents, and any other devices incorporating a camera, an inertialmeasurement unit, or both such as shown in any of the drawings, aregiven by way of example only, for illustration and discussion purposes.In operation, the eyewear device may be oriented in any other directionsuitable to the particular application of the eyewear device; forexample, up, down, sideways, or any other orientation. Also, to theextent used herein, any directional term, such as front, rear, inward,outward, toward, left, right, lateral, longitudinal, up, down, upper,lower, top, bottom, side, horizontal, vertical, and diagonal are used byway of example only, and are not limiting as to the direction ororientation of any camera or inertial measurement unit as constructed oras otherwise described herein.

Advanced AR technologies, such as computer vision and object tracking,may be used to produce a perceptually enriched and immersive experience.Computer vision algorithms extract three-dimensional data about thephysical world from the data captured in digital images or video. Objectrecognition and tracking algorithms are used to detect an object in adigital image or video, estimate its orientation or pose, and track itsmovement over time.

The term “pose” refers to the static position and orientation of anobject at a particular instant in time. The term “gesture” refers to theactive movement of an object, such as a hand, through a series of poses,sometimes to convey a signal or idea. The terms, pose and gesture, aresometimes used interchangeably in the field of computer vision and AR.As used herein, the terms “pose” or “gesture” (or variations thereof)are intended to be inclusive of both poses and gestures; in other words,the use of one term does not exclude the other.

Additional objects, advantages and novel features of the examples willbe set forth in part in the following description, and in part willbecome apparent to those skilled in the art upon examination of thefollowing and the accompanying drawings or may be learned by productionor operation of the examples. The objects and advantages of the presentsubject matter may be realized and attained by means of themethodologies, instrumentalities and combinations particularly pointedout in the appended claims.

Reference now is made in detail to the examples illustrated in theaccompanying drawings and discussed below.

FIG. 1A is a side view (right) of an example hardware configuration ofan eyewear device 100 which includes a touch-sensitive input device ortouchpad 181. As shown, the touchpad 181 may have a boundary that issubtle and not easily seen; alternatively, the boundary may be plainlyvisible or include a raised or otherwise tactile edge that providesfeedback to the user about the location and boundary of the touchpad181. In other implementations, the eyewear device 100 may include atouchpad on the left side.

The surface of the touchpad 181 is configured to detect finger touches,taps, and gestures (e.g., moving touches) for use with a GUI displayedby the eyewear device, on an image display, to allow the user tonavigate through and select menu options in an intuitive manner, whichenhances and simplifies the user experience.

Detection of finger inputs on the touchpad 181 can enable severalfunctions. For example, touching anywhere on the touchpad 181 may causethe GUI to display or highlight an item on the image display, which maybe projected onto at least one of the optical assemblies 180A, 180B.Double tapping on the touchpad 181 may select an item or icon. Slidingor swiping a finger in a particular direction (e.g., from front to back,back to front, up to down, or down to) may cause the items or icons toslide or scroll in a particular direction; for example, to move to anext item, icon, video, image, page, or slide. Sliding the finger inanother direction may slide or scroll in the opposite direction; forexample, to move to a previous item, icon, video, image, page, or slide.The touchpad 181 can be virtually anywhere on the eyewear device 100.

In one example, an identified finger gesture of a single tap on thetouchpad 181, initiates selection or pressing of a graphical userinterface element in the image presented on the image display of theoptical assembly 180A, 180B. An adjustment to the image presented on theimage display of the optical assembly 180A, 180B based on the identifiedfinger gesture can be a primary action which selects or submits thegraphical user interface element on the image display of the opticalassembly 180A, 180B for further display or execution.

As shown, the eyewear device 100 includes a right visible-light camera114B. As further described herein, two cameras 114A, 114B capture imageinformation for a scene from two separate viewpoints. The two capturedimages may be used to project a three-dimensional display onto an imagedisplay for viewing with 3D glasses.

The eyewear device 100 includes a right optical assembly 180B with animage display to present images, such as depth images. As shown in FIGS.1A and 1B, the eyewear device 100 includes the right visible-lightcamera 114B. The eyewear device 100 can include multiple visible-lightcameras 114A, 114B that form a passive type of three-dimensional camera,such as stereo camera, of which the right visible-light camera 114B islocated on a right corner 110B. As shown in FIGS. 1C-D, the eyeweardevice 100 also includes a left visible-light camera 114A.

Left and right visible-light cameras 114A, 114B are sensitive to thevisible-light range wavelength. Each of the visible-light cameras 114A,114B have a different frontward facing field of view which areoverlapping to enable generation of three-dimensional depth images, forexample, right visible-light camera 114B depicts a right field of view111B. Generally, a “field of view” is the part of the scene that isvisible through the camera at a particular position and orientation inspace. The fields of view 111A and 111B have an overlapping field ofview 304 (FIG. 3 ). Objects or object features outside the field of view111A, 111B when the visible-light camera captures the image are notrecorded in a raw image (e.g., photograph or picture). The field of viewdescribes an angle range or extent, which the image sensor of thevisible-light camera 114A, 114B picks up electromagnetic radiation of agiven scene in a captured image of the given scene. Field of view can beexpressed as the angular size of the view cone; i.e., an angle of view.The angle of view can be measured horizontally, vertically, ordiagonally.

In an example configuration, one or both visible-light cameras 114A,114B has a field of view of 100° and a resolution of 480 × 480 pixels.The “angle of coverage” describes the angle range that a lens ofvisible-light cameras 114A, 114B or infrared camera 410 (see FIG. 2A)can effectively image. Typically, the camera lens produces an imagecircle that is large enough to cover the film or sensor of the cameracompletely, possibly including some vignetting (e.g., a darkening of theimage toward the edges when compared to the center). If the angle ofcoverage of the camera lens does not fill the sensor, the image circlewill be visible, typically with strong vignetting toward the edge, andthe effective angle of view will be limited to the angle of coverage.

Examples of such visible-light cameras 114A, 114B include ahigh-resolution complementary metal-oxide-semiconductor (CMOS) imagesensor and a digital VGA camera (video graphics array) capable ofresolutions of 480p (e.g., 640 × 480 pixels), 720p, 1080p, or greater.Other examples include visible-light cameras 114A, 114B that can capturehigh-definition (HD) video at a high frame rate (e.g., thirty to sixtyframes per second, or more) and store the recording at a resolution of1216 by 1216 pixels (or greater).

The eyewear device 100 may capture image sensor data from thevisible-light cameras 114A, 114B along with geolocation data, digitizedby an image processor, for storage in a memory. The visible-lightcameras 114A, 114B capture respective left and right raw images in thetwo-dimensional space domain that comprise a matrix of pixels on atwo-dimensional coordinate system that includes an X-axis for horizontalposition and a Y-axis for vertical position. Each pixel includes a colorattribute value (e.g., a red pixel light value, a green pixel lightvalue, or a blue pixel light value); and a position attribute (e.g., anX-axis coordinate and a Y-axis coordinate).

In order to capture stereo images for later display as athree-dimensional projection, the image processor 412 (shown in FIG. 4 )may be coupled to the visible-light cameras 114A, 114B to receive andstore the visual image information. The image processor 412, or anotherprocessor, controls operation of the visible-light cameras 114A, 114B toact as a stereo camera simulating human binocular vision and may add atimestamp to each image. The timestamp on each pair of images allowsdisplay of the images together as part of a three-dimensionalprojection. Three-dimensional projections produce an immersive,life-like experience that is desirable in a variety of contexts,including virtual reality (VR) and video gaming.

FIG. 1B is a perspective, cross-sectional view of a right corner 110B ofthe eyewear device 100 of FIG. 1A depicting the right visible-lightcamera 114B of the camera system, and a circuit board. FIG. 1C is a sideview (left) of an example hardware configuration of an eyewear device100 of FIG. 1A, which shows a left visible-light camera 114A of thecamera system. FIG. 1D is a perspective, cross-sectional view of a leftcorner 110A of the eyewear device of FIG. 1C depicting the leftvisible-light camera 114A of the three-dimensional camera, and a circuitboard.

Construction and placement of the left visible-light camera 114A issubstantially similar to the right visible-light camera 114B, except theconnections and coupling are on the left lateral side 170A. As shown inthe example of FIG. 1B, the eyewear device 100 includes the rightvisible-light camera 114B and a circuit board 140B, which may be aflexible printed circuit board (PCB). A right hinge 126B connects theright corner 110B to a right temple 125B of the eyewear device 100. Insome examples, components of the right visible-light camera 114B, theflexible PCB 140B, or other electrical connectors or contacts may belocated on the right temple 125B or the right hinge 126B. A left hinge126B connects the left corner 110A to a left temple 125A of the eyeweardevice 100. In some examples, components of the left visible-lightcamera 114A, the flexible PCB 140A, or other electrical connectors orcontacts may be located on the left temple 125A or the left hinge 126A.

The right corner 110B includes corner body 190 and a corner cap, withthe corner cap omitted in the cross-section of FIG. 1B. Disposed insidethe right corner 110B are various interconnected circuit boards, such asPCBs or flexible PCBs, that include controller circuits for rightvisible-light camera 114B, microphone(s), low-power wireless circuitry(e.g., for wireless short range network communication via Bluetooth™),high-speed wireless circuitry (e.g., for wireless local area networkcommunication via Wi-Fi).

The right visible-light camera 114B is coupled to or disposed on theflexible PCB 140B and covered by a visible-light camera cover lens,which is aimed through opening(s) formed in the frame 105. For example,the right rim 107B of the frame 105, shown in FIG. 2A, is connected tothe right corner 110B and includes the opening(s) for the visible-lightcamera cover lens. The frame 105 includes a front side configured toface outward and away from the eye of the user. The opening for thevisible-light camera cover lens is formed on and through the front oroutward-facing side of the frame 105. In the example, the rightvisible-light camera 114B has an outward-facing field of view 111B(shown in FIG. 3 ) with a line of sight or perspective that iscorrelated with the right eye of the user of the eyewear device 100. Thevisible-light camera cover lens can also be adhered to a front side oroutward-facing surface of the right corner 110B in which an opening isformed with an outward-facing angle of coverage, but in a differentoutwardly direction. The coupling can also be indirect via interveningcomponents.

As shown in FIG. 1B, flexible PCB 140B is disposed inside the rightcorner 110B and is coupled to one or more other components housed in theright corner 110B. Although shown as being formed on the circuit boardsof the right corner 110B, the right visible-light camera 114B can beformed on the circuit boards of the left corner 110A, the temples 125A,125B, or the frame 105.

FIGS. 2A and 2B are perspective views, from the rear, of examplehardware configurations of the eyewear device 100, including twodifferent types of image displays. The eyewear device 100 is sized andshaped in a form configured for wearing by a user; the form ofeyeglasses is shown in the example. The eyewear device 100 can takeother forms and may incorporate other types of frameworks; for example,a headgear, a headset, or a helmet.

In the eyeglasses example, eyewear device 100 includes a frame 105including a left rim 107A connected to a right rim 107B via a bridge 106adapted to be supported by a nose of the user. The left and right rims107A, 107B include respective apertures 175A, 175B, which hold arespective optical element 180A, 180B, such as a lens and a displaydevice. As used herein, the term “lens” is meant to include transparentor translucent pieces of glass or plastic having curved or flat surfacesthat cause light to converge or diverge or that cause little or noconvergence or divergence.

Although shown as having two optical elements 180A, 180B, the eyeweardevice 100 can include other arrangements, such as a single opticalelement (or it may not include any optical element 180A, 180B),depending on the application or the intended user of the eyewear device100. As further shown, eyewear device 100 includes a left corner 110Aadjacent the left lateral side 170A of the frame 105 and a right corner110B adjacent the right lateral side 170B of the frame 105. The corners110A, 110B may be integrated into the frame 105 on the respective sides170A, 170B (as illustrated) or implemented as separate componentsattached to the frame 105 on the respective sides 170A, 170B.Alternatively, the corners 110A, 110B may be integrated into temples(not shown) attached to the frame 105.

In one example, the image display of optical assembly 180A, 180Bincludes an integrated image display. As shown in FIG. 2A, each opticalassembly 180A, 180B includes a suitable display matrix 177, such as aliquid crystal display (LCD), an organic light-emitting diode (OLED)display, or any other such display. Each optical assembly 180A, 180Balso includes an optical layer or layers 176, which can include lenses,optical coatings, prisms, mirrors, waveguides, optical strips, and otheroptical components in any combination. The optical layers 176A, 176B,... 176N (shown as 176A-N in FIG. 2A and herein) can include a prismhaving a suitable size and configuration and including a first surfacefor receiving light from a display matrix and a second surface foremitting light to the eye of the user. The prism of the optical layers176A-N extends over all or at least a portion of the respectiveapertures 175A, 175B formed in the left and right rims 107A, 107B topermit the user to see the second surface of the prism when the eye ofthe user is viewing through the corresponding left and right rims 107A,107B. The first surface of the prism of the optical layers 176A-N facesupwardly from the frame 105 and the display matrix 177 overlies theprism so that photons and light emitted by the display matrix 177impinge the first surface. The prism is sized and shaped so that thelight is refracted within the prism and is directed toward the eye ofthe user by the second surface of the prism of the optical layers176A-N. In this regard, the second surface of the prism of the opticallayers 176A-N can be convex to direct the light toward the center of theeye. The prism can optionally be sized and shaped to magnify the imageprojected by the display matrix 177, and the light travels through theprism so that the image viewed from the second surface is larger in oneor more dimensions than the image emitted from the display matrix 177.

In one example, the optical layers 176A-N may include an LCD layer thatis transparent (keeping the lens open) unless and until a voltage isapplied which makes the layer opaque (closing or blocking the lens). Theimage processor 412 on the eyewear device 100 may execute programming toapply the voltage to the LCD layer in order to produce an active shuttersystem, making the eyewear device 100 suitable for viewing visualcontent when displayed as a three-dimensional projection. Technologiesother than LCD may be used for the active shutter mode, including othertypes of reactive layers that are responsive to a voltage or anothertype of input.

In another example, the image display device of optical assembly 180A,180B includes a projection image display as shown in FIG. 2B. Eachoptical assembly 180A, 180B includes a laser projector 150, which is athree-color laser projector using a scanning mirror or galvanometer.During operation, an optical source such as a laser projector 150 isdisposed in or on one of the temples 125A, 125B of the eyewear device100. Optical assembly 180B in this example includes one or more opticalstrips 155A, 155B, ... 155N (shown as 155A-N in FIG. 2B) which arespaced apart and across the width of the lens of each optical assembly180A, 180B or across a depth of the lens between the front surface andthe rear surface of the lens.

As the photons projected by the laser projector 150 travel across thelens of each optical assembly 180A, 180B, the photons encounter theoptical strips 155A-N. When a particular photon encounters a particularoptical strip, the photon is either redirected toward the user’s eye, orit passes to the next optical strip. A combination of modulation oflaser projector 150, and modulation of optical strips, may controlspecific photons or beams of light. In an example, a processor controlsoptical strips 155A-N by initiating mechanical, acoustic, orelectromagnetic signals. Although shown as having two optical assemblies180A, 180B, the eyewear device 100 can include other arrangements, suchas a single or three optical assemblies, or each optical assembly 180A,180B may have arranged different arrangement depending on theapplication or intended user of the eyewear device 100.

As further shown in FIGS. 2A and 2B, eyewear device 100 includes a leftcorner 110A adjacent the left lateral side 170A of the frame 105 and aright corner 110B adjacent the right lateral side 170B of the frame 105.The corners 110A, 110B may be integrated into the frame 105 on therespective lateral sides 170A, 170B (as illustrated) or implemented asseparate components attached to the frame 105 on the respective sides170A, 170B. Alternatively, the corners 110A, 110B may be integrated intotemples 125A, 125B attached to the frame 105.

In another example, the eyewear device 100 shown in FIG. 2B may includetwo projectors, a left projector (not shown) and a right projector 150.The left optical assembly 180A may include a left display matrix 177A ora left set of optical strips (not shown) which are configured tointeract with light from the left projector. Similarly, the rightoptical assembly 180B may include a right display matrix (not shown) ora right set of optical strips 155A, 155B, ... 155N which are configuredto interact with light from the right projector 150. In this example,the eyewear device 100 includes a left display and a right display.

FIG. 3 is a diagrammatic depiction of a three-dimensional scene 306, aleft raw image 302A captured by a left visible-light camera 114A, and aright raw image 302B captured by a right visible-light camera 114B. Theleft field of view 111A may overlap, as shown, with the right field ofview 111B. The overlapping field of view 304 represents that portion ofthe image captured by both cameras 114A, 114B. The term ‘overlapping’when referring to field of view means the matrix of pixels in thegenerated raw images overlap by thirty percent (30%) or more.‘Substantially overlapping’ means the matrix of pixels in the generatedraw images - or in the infrared image of scene - overlap by fiftypercent (50%) or more. As described herein, the two raw images 302A,302B may be processed to include a timestamp, which allows the images tobe displayed together as part of a three-dimensional projection.

For the capture of stereo images, as illustrated in FIG. 3 , a pair ofraw red, green, and blue (RGB) images are captured of a real scene 306at a given moment in time - a left raw image 302A captured by the leftcamera 114A and right raw image 302B captured by the right camera 114B.When the pair of raw images 302A, 302B are processed (e.g., by the imageprocessor 412), depth images are generated. The generated depth imagesmay be viewed on an optical assembly 180A, 180B of an eyewear device, onanother display (e.g., the image display 580 on a mobile device 401), oron a screen. Likewise, cameras 570 of mobile device 401 (FIG. 5 ) may beused to capture images of a real scene 306 for processing (e.g., by CPU530) to generate depth images.

The generated depth images are in the three-dimensional space domain andcan comprise a matrix of vertices on a three-dimensional locationcoordinate system that includes an X axis for horizontal position (e.g.,length), a Y axis for vertical position (e.g., height), and a Z axis fordepth (e.g., distance). Each vertex may include a color attribute (e.g.,a red pixel light value, a green pixel light value, or a blue pixellight value); a position attribute (e.g., an X location coordinate, a Ylocation coordinate, and a Z location coordinate); a texture attribute;a reflectance attribute; or a combination thereof. The texture attributequantifies the perceived texture of the depth image, such as the spatialarrangement of color or intensities in a region of vertices of the depthimage.

Although the memory 434 is shown as integrated withhigh-speed circuitry 430, the memory 434 in other examples may be anindependent, standalone element of the eyewear device 100. In certainsuch examples, electrical routing lines may provide a connection througha chip that includes the high-speed processor 432 from the imageprocessor 412 or low-power processor 422 to the memory 434. In otherexamples, the high-speed processor 432 may manage addressing of memory434 such that the low-power processor 422 will boot the high-speedprocessor 432 any time that a read or write operation involving memory434 is needed.

As shown in FIG. 4 , the high-speed processor 432 of the eyewear device100 can be coupled to the camera system (visible-light cameras 114A,114B), the image display driver 442, the user input device 491, and thememory 434. As shown in FIG. 5 , the CPU 530 of the mobile device 401may be coupled to a camera system 570, a mobile display driver 582, auser input layer 591, and a memory 540A.

The output components of the eyewear device 100 include visual elements,such as the left and right image displays associated with each lens oroptical assembly 180A, 180B as described in FIGS. 2A and 2B (e.g., adisplay such as a liquid crystal display (LCD), a plasma display panel(PDP), a light emitting diode (LED) display, a projector, or awaveguide). The eyewear device 100 may include a user-facing indicator(e.g., an LED, a loudspeaker, or a vibrating actuator), or anoutward-facing signal (e.g., an LED, a loudspeaker). The image displaysof each optical assembly 180A, 180B are driven by the image displaydriver 442. In some example configurations, the output components of theeyewear device 100 further include additional indicators such as audibleelements (e.g., loudspeakers), tactile components (e.g., an actuatorsuch as a vibratory motor to generate haptic feedback), and other signalgenerators. For example, the device 100 may include a user-facing set ofindicators, and an outward-facing set of signals. The user-facing set ofindicators are configured to be seen or otherwise sensed by the user ofthe device 100. For example, the device 100 may include an LED displaypositioned so the user can see it, a one or more speakers positioned togenerate a sound the user can hear, or an actuator to provide hapticfeedback the user can feel. The outward-facing set of signals areconfigured to be seen or otherwise sensed by an observer near the device100. Similarly, the device 100 may include an LED, a loudspeaker, or anactuator that is configured and positioned to be sensed by an observer.

The mobile device 401 and the server system 498 may includealphanumeric, pointer-based, tactile, audio, and other input components.

In some examples, the eyewear device 100 includes a collection ofmotion-sensing components referred to as an inertial measurement unit472. The motion-sensing components may be micro-electro-mechanicalsystems (MEMS) with microscopic moving parts, often small enough to bepart of a microchip. The inertial measurement unit (IMU) 472 in someexample configurations includes an accelerometer, a gyroscope, and amagnetometer. The accelerometer senses the linear acceleration of thedevice 100 (including the acceleration due to gravity) relative to threeorthogonal axes (x, y, z). The gyroscope senses the angular velocity ofthe device 100 about three axes of rotation (pitch, roll, yaw).Together, the accelerometer and gyroscope can provide position,orientation, and motion data about the device relative to six axes (x,y, z, pitch, roll, yaw). The magnetometer, if present, senses theheading of the device 100 relative to magnetic north. The position ofthe device 100 may be determined by location sensors, such as a GPSunit, one or more transceivers to generate relative positioncoordinates, altitude sensors or barometers, and other orientationsensors. Such positioning system coordinates can also be received overthe wireless connections 425, 437 from the mobile device 401 via thelow-power wireless circuitry 424 or the high-speed wireless circuitry436.

The IMU 472 may include or cooperate with a digital motion processor orprogramming that gathers the raw data from the components and compute anumber of useful values about the position, orientation, and motion ofthe device 100. For example, the acceleration data gathered from theaccelerometer can be integrated to obtain the velocity relative to eachaxis (x, y, z); and integrated again to obtain the position of thedevice 100 (in linear coordinates, x, y, and z). The angular velocitydata from the gyroscope can be integrated to obtain the position of thedevice 100 (in spherical coordinates). The programming for computingthese useful values may be stored in memory 434 and executed by thehigh-speed processor 432 of the eyewear device 100.

The eyewear device 100 may optionally include additional peripheralsensors, such as biometric sensors, specialty sensors, or displayelements integrated with eyewear device 100. For example, peripheraldevice elements may include any I/O components including outputcomponents, motion components, position components, or any other suchelements described herein. For example, the biometric sensors mayinclude components to detect expressions (e.g., hand expressions, facialexpressions, vocal expressions, body gestures, or eye tracking), tomeasure bio signals (e.g., blood pressure, heart rate, body temperature,perspiration, or brain waves), or to identify a person (e.g.,identification based on voice, retina, facial characteristics,fingerprints, or electrical bio signals such as electroencephalogramdata), and the like.

The mobile device 401 may be a smartphone, tablet, laptop computer,access point, or any other such device capable of connecting witheyewear device 100 using both a low-power wireless connection 425 and ahigh-speed wireless connection 437. Mobile device 401 is connected toserver system 498 and network 495. The network 495 may include anycombination of wired and wireless connections.

The handcrafted AR system 400, as shown in FIG. 4 , includes a computingdevice, such as mobile device 401, coupled to an eyewear device 100 overa network. The handcrafted AR system 400 includes a memory for storinginstructions and a processor for executing the instructions. Executionof the instructions of the handcrafted AR system 400 by the processor432 configures the eyewear device 100 to cooperate with the mobiledevice 401. The handcrafted AR system 400 may utilize the memory 434 ofthe eyewear device 100 or the memory elements 540A, 540B, 540C of themobile device 401 (FIG. 5 ). Also, the handcrafted AR system 400 mayutilize the processor elements 432, 422 of the eyewear device 100 or thecentral processing unit (CPU) 530 of the mobile device 401 (FIG. 5 ). Inaddition, the handcrafted AR system 400 may further utilize the memoryand processor elements of the server system 498. In this aspect, thememory and processing functions of the handcrafted AR system 400 can beshared or distributed across the processors and memories of the eyeweardevice 100, the mobile device 401, and the server system 498.

The memory 434, in some example implementations, includes or is coupledto a hand gesture library 480. The library of hand gestures 480 includesa large number of poses and gestures, with the hand in various positionsand orientations. The stored poses and gestures are suitable for readycomparison to a hand shape that is detected in an image. The library 480includes three-dimensional coordinates for a large number of landmarks,from the wrist to the fingertips. For example, a hand gesture recordstored in the library 480 may include a hand gesture identifier (e.g.,pointing finger, thumb and finger making an L-shape, closed fist, openpalm, relaxed hand, grasping an object, pinching, spreading), a point ofview or a directional reference (e.g., palmar side visible, dorsal,lateral), and other information about orientation, along withthree-dimensional coordinates for the wrist, the fifteen interphalangealjoints, the five fingertips and other skeletal or soft-tissue landmarks.The process of detecting a hand shape, in some implementations, involvescomparing the pixel-level data in one or more captured frames of videodata to the hand gestures stored in the library 480 until a good matchis found.

The memory 434 additionally includes, in some example implementations,an object control application 481, a localization system 482, and animage processing system 483. In a handcrafted AR system 400 in which acamera is capturing frames of video data, the object control application481 configures the processor 432 to control the movement of an AR object608 on a display in response to detecting one or more hand shapes orgestures via a camera system or on a user input layer of a display, forexample. The localization system 482 configures the processor 432 toobtain localization data for use in determining the position of theeyewear device 100 relative to the physical environment. Thelocalization data may be derived from a series of images, an IMU unit472, a GPS unit, or a combination thereof. The image processing system483 configures the processor 432 to present a captured still image on adisplay of an optical assembly 180A, 180B in cooperation with the imagedisplay driver 442 and the image processor 412.

FIG. 5 is a high-level functional block diagram of an example mobiledevice 401. Mobile device 401 includes a flash memory 540A which storesprogramming to be executed by the CPU 530 to perform all or a subset ofthe functions described herein. The mobile device 401 may include one ormore speakers. The one or more speakers are driven by audio processorunder control of the CPU 530. The speakers are for presenting audiosignals including, for example, a beat track. The audio processor iscoupled to the speakers in order to control the presentation of sound.

The mobile device 401 may include a camera 570 that comprises at leasttwo visible-light cameras (first and second visible-light cameras withoverlapping fields of view) or at least one visible-light camera and adepth sensor with substantially overlapping fields of view. Flash memory540A may further include multiple images or video, which are generatedvia the camera 570.

As shown, the mobile device 401 includes an image display 580, a mobiledisplay driver 582 to control the image display 580, and a displaycontroller 584. In the example of FIG. 5 , the image display 580includes a user input layer 591 (e.g., a touchscreen) that is layered ontop of or otherwise integrated into the screen used by the image display580.

Examples of touchscreen-type mobile devices that may be used include(but are not limited to) a smart phone, a personal digital assistant(PDA), a tablet computer, a laptop computer, or other portable device.However, the structure and operation of the touchscreen-type devices isprovided by way of example; the subject technology as described hereinis not intended to be limited thereto. For purposes of this discussion,FIG. 5 therefore provides a block diagram illustration of the examplemobile device 401 with a user interface that includes a touchscreeninput layer 891 for receiving input (by touch, multi-touch, or gesture,and the like, by hand, stylus, or other tool) and an image display 580for displaying content.

As shown in FIG. 5 , the mobile device 401 includes at least one digitaltransceiver (XCVR) 510, shown as WWAN XCVRs, for digital wirelesscommunications via a wide-area wireless mobile communication network.The mobile device 401 also includes additional digital or analogtransceivers, such as short-range transceivers (XCVRs) 520 forshort-range network communication, such as via NFC, VLC, DECT, ZigBee,Bluetooth™, or Wi-Fi. For example, short range XCVRs 520 may take theform of any available two-way wireless local area network (WLAN)transceiver of a type that is compatible with one or more standardprotocols of communication implemented in wireless local area networks,such as one of the Wi-Fi standards under IEEE 802.11.

To generate location coordinates for positioning of the mobile device401, the mobile device 401 can include a global positioning system (GPS)receiver. Alternatively, or additionally the mobile device 401 canutilize either or both the short range XCVRs 520 and WWAN XCVRs 510 forgenerating location coordinates for positioning. For example, cellularnetwork, Wi-Fi, or Bluetooth™ based positioning systems can generatevery accurate location coordinates, particularly when used incombination. Such location coordinates can be transmitted to the eyeweardevice over one or more network connections via XCVRs 510, 520.

The client device 401 in some examples includes a collection ofmotion-sensing components referred to as an inertial measurement unit(IMU) 572 for sensing the position, orientation, and motion of theclient device 401. The motion-sensing components may bemicro-electro-mechanical systems (MEMS) with microscopic moving parts,often small enough to be part of a microchip. The inertial measurementunit (IMU) 572 in some example configurations includes an accelerometer,a gyroscope, and a magnetometer. The accelerometer senses the linearacceleration of the client device 401 (including the acceleration due togravity) relative to three orthogonal axes (x, y, z). The gyroscopesenses the angular velocity of the client device 401 about three axes ofrotation (pitch, roll, yaw). Together, the accelerometer and gyroscopecan provide position, orientation, and motion data about the devicerelative to six axes (x, y, z, pitch, roll, yaw). The magnetometer, ifpresent, senses the heading of the client device 401 relative tomagnetic north.

The IMU 572 may include or cooperate with a digital motion processor orprogramming that gathers the raw data from the components and compute anumber of useful values about the position, orientation, and motion ofthe client device 401. For example, the acceleration data gathered fromthe accelerometer can be integrated to obtain the velocity relative toeach axis (x, y, z); and integrated again to obtain the position of theclient device 401 (in linear coordinates, x, y, and z). The angularvelocity data from the gyroscope can be integrated to obtain theposition of the client device 401 (in spherical coordinates). Theprogramming for computing these useful values may be stored in on ormore memory elements 540A, 540B, 540C and executed by the CPU 530 of theclient device 401.

The transceivers 510, 520 (i.e., the network communication interface)conforms to one or more of the various digital wireless communicationstandards utilized by modern mobile networks. Examples of WWANtransceivers 510 include (but are not limited to) transceiversconfigured to operate in accordance with Code Division Multiple Access(CDMA) and 3rd Generation Partnership Project (3GPP) networktechnologies including, for example and without limitation, 3GPP type 2(or 3GPP2) and LTE, at times referred to as “4G.” For example, thetransceivers 510, 520 provide two-way wireless communication ofinformation including digitized audio signals, still image and videosignals, web page information for display as well as web-related inputs,and various types of mobile message communications to/from the mobiledevice 401.

The mobile device 401 further includes a microprocessor that functionsas a central processing unit (CPU); shown as CPU 530 in FIG. 4 . Aprocessor is a circuit having elements structured and arranged toperform one or more processing functions, typically various dataprocessing functions. Although discrete logic components could be used,the examples utilize components forming a programmable CPU. Amicroprocessor for example includes one or more integrated circuit (IC)chips incorporating the electronic elements to perform the functions ofthe CPU. The CPU 530, for example, may be based on any known oravailable microprocessor architecture, such as a Reduced Instruction SetComputing (RISC) using an ARM architecture, as commonly used today inmobile devices and other portable electronic devices. Of course, otherarrangements of processor circuitry may be used to form the CPU 530 orprocessor hardware in smartphone, laptop computer, and tablet.

The CPU 530 serves as a programmable host controller for the mobiledevice 401 by configuring the mobile device 401 to perform variousoperations, for example, in accordance with instructions or programmingexecutable by CPU 530. For example, such operations may include variousgeneral operations of the mobile device, as well as operations relatedto the programming for applications on the mobile device. Although aprocessor may be configured by use of hardwired logic, typicalprocessors in mobile devices are general processing circuits configuredby execution of programming.

The mobile device 401 includes a memory or storage system, for storingprogramming and data. In the example, the memory system may include aflash memory 540A, a random-access memory (RAM) 540B, and other memorycomponents 540C, as needed. The RAM 540B serves as short-term storagefor instructions and data being handled by the CPU 530, e.g., as aworking data processing memory. The flash memory 540A typically provideslonger-term storage.

Hence, in the example of mobile device 401, the flash memory 540A isused to store programming or instructions for execution by the CPU 530.Depending on the type of device, the mobile device 401 stores and runs amobile operating system through which specific applications areexecuted. Examples of mobile operating systems include Google Android,Apple iOS (for iPhone or iPad devices), Windows Mobile, Amazon Fire OS,RIM BlackBerry OS, or the like.

The memory 540 may additionally include, in some exampleimplementations, an object control application 481, a localizationsystem 482, and an image processing system 483, which are discussedabove with reference to eyewear device 100. In a mobile device 401 inwhich cameras 570 are capturing frames of video data, the object controlapplication 481 configures the CPU 530 to control the movement of an ARobject 608 on a display in response to detecting one or more gestures ona user input layer of a display, for example. The localization system482 configures the CPU 530 to obtain localization data for use indetermining the position of the mobile device 401 relative to thephysical environment. The localization data may be derived from a seriesof images, an IMU unit 572, a GPS unit, or a combination thereof. Theimage processing system 483 configures the CPU 530 to present a capturedstill image on a display in cooperation with the image display driver582.

The processor 432 within the eyewear device 100 or the CPU 530 withinthe mobile device 401 may construct a map of the environment surroundingthe respective eyewear device 100 or mobile device 401, determine alocation of the eyewear device/mobile device within the mappedenvironment, and determine a relative position of the eyeweardevice/mobile device to one or more AR or physical objects in the mappedenvironment. The processor 432/530 may construct the map and determinelocation and position information using a simultaneous localization andmapping (SLAM) algorithm applied to data received from one or moresensors. Sensor data includes images received from one or both of thecameras 114A, 114B, 570, distance(s) received from a laser range finder,position information received from a GPS unit, motion and accelerationdata received from an IMU 472/572, or a combination of data from suchsensors, or from other sensors that provide data useful in determiningpositional information.

In the context of AR, a SLAM algorithm is used to construct and update amap of an environment, while simultaneously tracking and updating thelocation of a device (or a user) within the mapped environment. Themathematical solution can be approximated using various statisticalmethods, such as particle filters, Kalman filters, extended Kalmanfilters, and covariance intersection. In one example, a system thatincludes a high-definition (HD) video camera that captures video at ahigh frame rate (e.g., thirty frames per second), the SLAM algorithmupdates the map and the location of objects at least as frequently asthe frame rate; in other words, calculating and updating the mapping andlocalization thirty times per second.

Sensor data includes image(s) received from one or both cameras 114A,114B, 570 distance(s) received from a laser range finder, positioninformation received from a GPS unit, motion and acceleration datareceived from an IMU 472/572, or a combination of data from suchsensors, or from other sensors that provide data useful in determiningpositional information.

FIG. 6A depicts an example physical environment 600 along with elementsthat are useful when using a SLAM application and other types oftracking applications (e.g., natural feature tracking (NFT)) with an ARdevice such as the eyewear device 100. A user 602 of the eyewear device100 is present in an example physical environment 600 (which, in FIG.6A, is an interior room). The processor 432 of the eyewear device 100determines its position with respect to one or more objects 604 withinthe environment 600 using captured images, constructs a map of theenvironment 600 using a coordinate system (x, y, z) for the environment600, and determines its position within the coordinate system.Additionally, the processor 432 determines a head pose (roll, pitch, andyaw) of the eyewear device 100 within the environment by using two ormore location points (e.g., three location points 606 a, 606 b, and 606c) associated with a single object 604 a, or by using one or morelocation points 606 associated with two or more objects 604 a, 604 b,604 c. The processor 432 of the eyewear device 100 may position an ARobject 608 (such as the bear shown in FIGS. 6A and 6B) within theenvironment 600 for viewing during an AR experience. The AR object 608may be associated with a surface such as a top 611 of a table 609 withthe environment 600, e.g., based on location coordinates.

The localization system 482 in some examples associates a virtual marker610 a with an AR object 608 in the environment 600. In AR, markers areregistered at locations in the environment to assist devices with thetask of tracking and updating the location of users, devices, andobjects (virtual and physical) in a mapped environment. Markers aresometimes registered to a high-contrast physical object, such as therelatively dark object, such as the framed picture 604 a, mounted on alighter-colored wall, to assist cameras and other sensors with the taskof detecting the marker. The markers may be preassigned or may beassigned by the eyewear device 100 upon entering the environment.

Markers can be encoded with or otherwise linked to information. A markermight include position information, a physical code (such as a bar codeor a QR code; either visible to the user or hidden), or a combinationthereof. A set of data associated with the marker is stored in thememory 434 of the eyewear device 100. The set of data includesinformation about the marker 610 a, the marker’s position (location andorientation), one or more virtual objects, or a combination thereof. Themarker position may include three-dimensional coordinates for one ormore marker landmarks 616 a, such as the corner of the generallyrectangular marker 610 a shown in FIG. 6 . The marker location may beexpressed relative to real-world geographic coordinates, a system ofmarker coordinates, a position of the eyewear device 100, or othercoordinate system. The one or more virtual objects associated with themarker 610 a may include any of a variety of material, including stillimages, video, audio, tactile feedback, executable applications,interactive user interfaces and experiences, and combinations orsequences of such material. Any type of content capable of being storedin a memory and retrieved when the marker 610 a is encountered orassociated with an assigned marker may be classified as a virtual objectin this context. The bear 608 shown in FIG. 6A, for example, is avirtual object displayed, either 2D or 3D, at a marker location.

In one example, the marker 610 a may be registered in memory as beinglocated near and associated with a physical object 604 a (e.g., theframed work of art shown in FIG. 6A). In another example, the marker maybe registered in memory as being a particular position with respect tothe eyewear device 100.

FIG. 6B depicts another example physical environment 600 along withelements that are useful when using a SLAM application and other typesof tracking applications (e.g., natural feature tracking (NFT)) with anAR device such as the mobile device 401. Similar to the processor 432 ofthe eyewear device 100, the CPU 530 of the mobile device 401 determinesits position with respect to one or more objects 604 within theenvironment 600 using captured images, constructs a map of theenvironment 600 using a coordinate system (x, y, z) for the environment600, and determines its position within the coordinate system.Additionally, the CPU 530 determines a pose (roll, pitch, and yaw) ofthe mobile device 401 within the environment by using two or morelocation points (e.g., three location points 606 a, 606 b, and 606 c)associated with a single object 604 a, or by using one or more locationpoints 606 associated with two or more objects 604 a, 604 b, 604 c. TheCPU 530 of the mobile device 401 may position an AR object 608 (such asthe bear shown in FIG. 6B) within the environment 600 for viewing duringan AR experience.

FIG. 7A is a perspective illustration of an example hand gesturecontrolling AR objects on an example display 180B. In this example, theeyewear device includes a semi-transparent image display 180B which, asdescribed herein, may include a semi-transparent lens layer and adisplay matrix layer configured to present images on the lens of theeyewear device. The AR object 608 is presented as an overlay relativethe physical environment 600. The effect, as shown, allows the viewer tosee and interact with the AR object 608 while the surroundingenvironment 600 (including table 609) also remains visible through thedisplay 180B. In this example, the AR object 608 is anchored to thephysical environment 600 (i.e., on the tabletop), as opposed toappearing at a persistent location on the display 180B.

The hand 650 and hand shapes are detected and differentiated from otherelements in the physical environment 600 as viewed through thesemi-transparent display 180B and captured by the camera system 114. Forexample, a hand 650 with the index finger 621 extended may result in thevirtual element 608 being moved to a position on a surface of a physicalobject where a vector extending from the index finger intersects thesurface. In other examples, a first gesture or series of gestures suchas swiping right/left/up/down with the index finger 621 extended may beinterpreted to move through selection options and a second gesture orseries of gestures such as a closed fist may be interpreted as a finalselection. The physical environment 600, of course, may be much morecomplex than the simple room shown. The camera system 114 typically hasa camera field of view that captures images and video beyond the limitsof the display 180B. In this aspect, the image processing system 483detects hand shapes which may be located outside the view through thedisplay 180B, but within the camera field of view.

FIG. 7B is a perspective illustration of an example control forcontrolling AR objects 608 on an example display 580. In this example,the mobile device 401 includes a display 580 having a user input layer591 responsive to human touch. The AR object 608 is presented as anoverlay relative the physical environment 600. The effect, as shown,allows the viewer to see and interact with the AR object 608 while thesurrounding environment 600 also remains visible on the display 180B. Inthis example, the AR object 608 is anchored to the physical environment600 (i.e., on the tabletop), as opposed to appearing at a persistentlocation on the display 180B.

A user may interact with the AR object 608 by pressing select areas onthe user input layer 591. For example, dragging a finger on the userinput layer above a surface (such as a tabletop) may result in the ARobject 608 moving along the path made by the finger. In the illustratedexample, selection areas are presented on the display 580 in areas ofthe user input layer 591 corresponding to particular actions. Forexample, pressing a right selection area 750 may cause a first action tooccur (e.g., raise the bear’s left arm), pressing a left selection area752 may cause a second action to occur (e.g., raise the bear’s rightarm), and pressing a top selection area 754 may cause a third action tooccur (e.g., the bear jumps). The physical environment 600, of course,may be much more complex than the simple room shown.

FIG. 8 depicts an example AR primary object in the form of a bear 608.The primary object has a head 802, a right arm 804, a right shoulderjoint 806, a left arm 808, a left shoulder joint 810, a right leg 812, aright hip joint 814, a left leg 816, and a left hip joint 818. In anexample, the AR primary object is associated with x-y-z coordinates 820for defining the position of the AR primary object in the environment600. The AR primary object may be associated with additional x-y-zcoordinates that are assigned to different portions of the AR primaryobject (e.g., left arm 808) for use in positioning those portion s inthe environment 600 in response to user actions.

The illustrated AR primary object additionally includes selectablefeatures. In one example, a selectable feature is a scroll 824positioned within a pocket 822. In another example, the selectablefeature is a tag 826 connected to the primary object. Selection of theselectable feature may result in presentation of AR overlays includingproof of effort, e.g., presentation of a certificate includingstatistics based on AR object generation data gathered duringdevelopment of the AR primary object or a time lapsed video of thedevelopment from start to finish.

The selection may be a virtual selection or a physical selection. For avirtual selection, the processor 412/530 may identify an index finger ofa hand in images gathered by a camera in a location corresponding to thevirtual location of the selectable feature using computer visionprogrammed or trained to identify hand gestures within the capturedimages. In another example, the selection is a physical tap on, forexample, a user input layer 591 of a display 580 adjacent the selectablefeature presented on the display 580.

Although a bear has been used throughout the examples as the AR primaryobject, essentially any 2D or 3D object may be selected as the ARprimary object. For example, the AR primary object may be anotherpredefined animal (e.g., a chicken), something the user selects fromtheir environment (e.g., a coffee mug), or something received by theuser from another user.

FIGS. 9A, 9B, 9C, and 9D are respective flow charts 900, 930, 940, and950 depicting example methods of generating and sharing AR handcraftedobjects and capturing effort put into the generation of the ARhandcrafted objects. Although the steps are described with reference tothe eyewear device 100 and mobile device 401 described herein, otherimplementations of the steps described, for other types of devices, willbe understood by one of skill in the art from the description herein.One or more of the steps shown and described may be performedsimultaneously, in a series, in an order other than shown and described,or in conjunction with additional steps. Some steps may be omitted or,in some applications, repeated.

At block 901, initiate AR object generation and begin capturing data foruse in generating proof of effort data. In one example, initiation of ARobject generation (e.g., in response to a user making a selection tobegin in an application for generating an AR object) also begins thecapture of data. The processor 432/530 may capture the data and store itin memory. The captured data may include one or more of images viewed ona display (either all images or periodically captured images, e.g., onceper second to generate a time lapse series of images), gestures used,actions selected, images considered, audio considered, etc.

At block 902, capture images of a scene. A camera system (e.g., visiblelight camera 114A-B and image processor 412 of eyewear device or cameras570 and an image processor of mobile device 401) capture images of thescene within a view of view of the system cameras. In one example, thecamera system captures frames a video data. In some implementations, thehigh-speed processor 432 of the eyewear device 100 or CPU 530 of themobile device 401 stores the captured frames of video data as thewearer/user moves through a physical environment 600.

The camera systems, in some implementations, include one or morehigh-resolution, digital cameras equipped with a CMOS image sensorcapable of capturing high-definition still images and high-definitionvideo at relatively high frame rates (e.g., thirty frames per second ormore). Each frame of digital video includes depth information for aplurality of pixels in the image. In this aspect, the camera systemserves as a high-definition scanner by capturing a detailed input imageof the physical environment. The camera system, in some implementations,includes a pair of high-resolution digital cameras spaced apart toacquire a left-camera raw image and a right-camera raw image. Whencombined, the raw images form an input image that includes a matrix ofthree-dimensional pixel locations.

At block 904, identify an object receiving surface. A processing systemincluding a processor (e.g., HS processor 432 or CPU 530) identifies anobject receiving surface with an environment. In one example, theprocessing system identifies a flat horizontal surface of a predefinedsize (e.g., greater than 1 foot by 1 foot) closest to a central point ofthe field of view as the object receiving surface. Coordinatescorresponding to the identified object receiving surface are recordedfor use in positioning objects with respect to the object receivingsurface.

Processing system identifies the flat horizontal surfaces by applyingmachine vision techniques to the captured images (Block 902). Althoughthe object receiving surface is described in the examples herein as aflat horizontal surface of a predefined size, the object receivingsurface can be essentially any surface desired by a designer or user forplacing the AR primary object (e.g., a flat vertical surface, a ceiling,a floor, etc.).

At block 906, identify a customizable AR primary object/activity. In oneexample, a user selects from predefined customizable AR primaryobjects/activities via a user input system (e.g., hand gestures capturedand processed by eyewear device 401 or user layer 591 of mobile device401). In other example, the customizable AR primary object/activity maybe generated by the user. For example, the user may capture an image ofan object (e.g., a coffee mug given to her by a friend) and designatethat object as a customizable AR primary object.

The customizable AR primary object is associated with at least one setof primary object coordinates for use in positioning the AR primaryobject in the environment 600. The coordinates of the AR primary objectmay be set to match the coordinates of the center of the objectreceiving surface. The user may be presented with the predefinedcustomizable AR primary objects/activities on a display of the ARdevice. FIGS. 10A - 10C depicts example predefined AR primaryobjects/activities for presentation on a display of a mobile device 401.Suitable modifications for presenting on displays of an eyewear device100 will be understood by one of skill in the art from the descriptionherein.

FIG. 10A depicts a bear AR primary object 608 associated with a craftactivity 1010, FIG. 10B depicts the bear AR primary object 608associated with a comfort activity 1012, and FIG. 10C depicts the bearAR primary object 608 associated with a perform activity 1014. A usermay swipe left or tap left arrow 1002 to move to a prior AR primaryobject/activity and may swipe right or tap right arrow 1004 to move tothe next prior AR primary object/activity. The user may tap the centerof the display or use a predefined hand gesture to select the AR primaryobjects/activities.

At block 908, generate AR overlays. In one example, an image processingsystem (e.g., image processor 412 of eyewear device 100 or CPU 530 ofmobile device 401) generates the AR overlays. The AR overlays includethe identified customizable AR primary object positioned within theenvironment 600 adjacent (e.g., on) the object receiving surface. Theimage processing system positions the customizable AR primary objectwith respect to the object receiving surface responsive to theirrespective coordinates.

At block 910, present the AR overlays. A display system (e.g., imagedisplay driver 442 and displays 180 of the eyewear device 100 or driver582 and display 580 of the mobile device 401) presents the AR overlaysunder control of the processing system. The display system has a viewingarea corresponding to the field of view of the camera system. In oneexample, the viewing area is the same size as the field of view. Inanother example, the viewing area is smaller than the field of view.

At block 912, receive customization commands. In one example, a userselects from predefined customization commands via a user input system.The customization commands may be solicited through predefinedselectable actions associated with each of the customizable AR primaryobjects/activities. In accordance with this example, the user ispresented with the predefined selectable actions on a display of the ARdevice. FIGS. 11A - 11C, 12A and 12B depict example predefinedselectable actions for presentation on a display of a mobile device 401.After completing a selectable action, the user has the option to sendthe customizable AR primary object as customized by selecting send 1101Bor to save (e.g., to send later or to add other selectable actions) byselecting save 1101A. Suitable modifications for presenting on displaysof an eyewear device 100 will be understood by one of skill in the artfrom the description herein. Whether corresponding sounds are presentedis controlled by actuating noise selection 1101C.

FIG. 11A depicts predefined customization commands for a craft activity1010 (FIG. 10A). In one example, the customizable AR primary objectincludes an image receiving area 1102. An outline of the image receivearea 1102 may be visible as shown or not visible. The predefinedcustomization commands include draw 1104A, media 1104B, and voice 1104C.Selection of draw 1104A results in display of a sketch pad that the usercan “draw” on using their finger or an electronic pen compatible withthe device. Upon completion of the drawing, the drawing is added to theimage receiving area or another area that is predefined or defined bythe user. Selection of media 1104B results in the user being able toselect a camera (e.g., to capture images in the environment 600) or fromstored media (e.g., from the camera roll). Upon selection of the desiredmedia, the media is added to the image receiving area or another areathat is predefined or defined by the user. Selection of voice 1104Cresults in the user being able to select a microphone (e.g., to capturea spoken message) or from stored media (e.g., from a song list). Uponselection of the desired media, the media is added to a file associatedwith the customizable AR primary object. Flow chart 930 (FIG. 9B)depicts example steps for adding an image using processing system. Atblock 932, receive an image selection for the image selection area. Atblock 934 obtain an image from a camera or from memory. At block 936,optionally modify the image (e.g., by cropping or rotating). At block928, apply the image (as optionally modified) to the image receivingarea. The number of images presented prior to receiving an imageselection or the time spent modifying an image may be recorded anddesignated proof of effort data. In one example, images includingpotentially sensitive content are blurred (e.g., by applying an imageprocessing algorithm that changes the depth of field) in order to avoidaccidentally including potentially sensitive content in the proof ofeffort data. Potentially sensitive content may be identified as anyvideo or image that are not included in the final AR object.

FIG. 11B depicts predefined customization commands for a comfortactivity 1012 (FIG. 10B). In one example, the customizable AR primaryobject is paired with a prop object. The prop object may be anothervirtual object or a physical object in the environment designated by theuser. The positioning of the customizable AR primary object with respectto the prop object is managed (e.g., by the processing system) throughtheir respective coordinates.

The predefined customization commands include hug 1106A, kiss 1106B, andlift 1106C. Selection of hug 1106A results in display of the AR primaryobject 608 embracing the prop object. The hug selection 1106A mayinclude a sliding scale 1008 with an indicator 1110 on the sliding scale1008 representing an intensity of the hug (e.g., the closer therespective coordinates of the AR primary object and the prop object).Selection of kiss 1106B results in display of the AR primary object 608kissing the prop object. Selection of lift 1106C results in display ofthe AR primary object 608 lifting the prop object (and optionallytwirling). Flow chart 940 (FIG. 9C) depicts example steps for performingan action (optionally with a prop). At block 942, receive an actionselection for customizable AR primary object. At block 944, identify aprop (physical or virtual). At block 946, adjust the AR primary objectresponsive to the action selection and optional prop.

FIG. 11C depicts predefined customization commands for a performanceactivity 1014 (FIG. 10C). In one example, the customizable AR primaryobject is paired with an activity prop object (e.g., a drum set fordrumming. The activity prop object is another virtual object. Thepredefined customization commands for a drum set prop include hi-hat1108A, snare 1108B, and kick 1108C. Selection of the hi-hat 1108Aresults in display of the AR primary object 608 hitting the hi hat ofthe drum set and presentation of a corresponding noise via speakers.Selection of the snare 1108B results in display of the AR primary object608 hitting the snare of the drum set and presentation of acorresponding noise. Selection of kick 1108C results in display of theAR primary object 608 actuating the base drum and presentation of acorresponding noise.

The activities can be further customized using the features depicted inFIGS. 12A and 12B. FIG. 12A depicts predefined confetti options 1204A,B, C, and D depicted in a selection area 1202. The confetti options canbe accessed by tapping the scene on a display of a mobile device. Once aconfetti option is selected, it is positioned in the scene correspondingto where the screen was tapped. For example, as illustrated in FIG. 12Bfor the drum set performance activity, the user taps on the screen,which presents the custom confetti options. Selection of a particularconfetti (e.g., sun 1204C) results in that confetti being positioned onthe screen in the area where the user tapped. The user may return to theactivity without adding confetti by tapping back 1201.

At block 914, generate handcrafted AR overlays including customizationsresponsive to the customization commands. In one example, an imageprocessing system (e.g., image processor 412 of eyewear device 100 orCPU 530 of mobile device 401) generates the handcrafted AR overlays. Thehandcrafted AR overlays include the identified customizable AR primaryobject with applied customizations positioned within the environment 600adjacent (e.g., on) the object receiving surface. The image processingsystem positions the handcrafted AR primary object with respect to theobject receiving surface responsive to their respective coordinates.

At block 916, present the handcrafted AR overlays. A display system(e.g., image display driver 442 and displays 180 of the eyewear device100 or driver 582 and display 580 of the mobile device 401) presents thehandcrafted AR overlay under control of the processing system.

At block 918, selectively save the handcrafted AR overlays as thehandcrafted AR object. In one example, the user selects a “save”indicator presented on a display after each action to have thecorresponding AR overlays included in the final handcrafted AR object.In another example, the corresponding handcrafted AR overlays areincluded in the final handcrafted AR object unless the user selects a“discard” indicator presented on a display by a processor after eachaction. The processing system records the handcrafted AR overlays as thefinal handcrafted AR object in memory (e.g., memory 434 of eyeweardevice 100 or memory 540 of mobile device 401). Note that allhandcrafted AR overlays (or a sampled subset) may also be stored for usein generating proof of effort. Alternatively, all handcrafted ARoverlays may be stored and entries in a table may be used to indicatewhether a handcrafted overlay forms part of the final handcrafted ARobject.

At block 920, terminate AR object generation and end capturing data foruse in generating proof of effort data. In one example, termination ofAR object generation (e.g., in response to a user making a selection toend in the application for generating an AR object) also ends thecapture of data.

At block 922, generate proof of effort data. In one of example, theproof of effort data is representative images displayed of a displayduring generation of the AR object, e.g., all handcrafted AR overlays(or a sampled subset). In accordance with this example, the processor432/530 designates these handcrafted AR overlay as proof of effort data.In another example, the proof of effort data is all customizationcommands/action performed during the creation of the AR object. Inaccordance with this example, the processor 432/530 designates thesecommands/actions as proof of effort data. In another example, the proofof effort data is a statistic such as total time (e.g., as captured by acounter running on the processor 432/530) from the beginning to the endof data capture during the creation of the AR object, the total numberof images considered prior to selection, or the total number of songsconsidered prior to selection. In another example, the proof of effortdata is a link such as a QR code including an address for retrieving theproof of effort data from a globally accessible memory location.

At block 924, assemble a handcrafted AR file including proof of effortdata. The processing system retrieve the handcrafted AR overlays and theproof of effort data from memory and combines them into a file fortransmission to another augmented reality device and playback thereon.Suitable file formats include a 3D file format such as USDZ, FBX, etc.In one example, the proof of effort data is combined with the AR objectby incorporating it into the AR object, e.g., for retrieval when the ARobject is presented on another AR device.

At block 926, transmit the handcrafted AR file. The processing systemtransmits the file via a wired or wireless connection via a transceiverfor reception by a transceiver of another device.

The other device, upon receipt of the handcrafted AR file including theproof of effort data, captures, via another camera system, images of theother scene in the field of view of the other device (e.g., as describedwith reference to block 902), identifies another object receivingsurface and corresponding surface coordinates within the other scene(e.g., as described with reference to block 904), generates handcraftedAR overlays from the handcrafted AR file including the customizationsassociated with the customizable AR primary object for positioningadjacent the other object receiving surface responsive to the primaryobject coordinates and the surface coordinates within the other scene(e.g., as described with reference to block 914), and presents, viaanother display system, the handcrafted AR overlays (e.g., as describedwith reference to block 916). The proof of effort data may beincorporated into the AR object and accessed by selecting a proof ofeffort data selectable feature on the AR object in the handcrafter ARoverlays.

Flowchart 950 depicts example steps for adding a soundtrack to thehandcrafted AR file. At block 952, receive an audio personalizationselection. The processor system may receive an audio personalizationselection via selection of a selection option presented on a display. Atblock 954, the processor system presents audio options on a display. Atdecision block 956, the processor determines whether a live recording isselected. If a live recording is selected, at block 958, live audio isrecorded via a microphone and stored in memory as a soundtrack. At block960, present prerecorded soundtrack selection option (e.g., retrievedfrom memory). At block 962, receive a soundtrack selection from thepresented options and identify as the soundtrack. At block 964,optionally receive soundtrack adjustment (e.g., select only the chorusfrom a song. At block 966, the soundtrack (as optionally adjusted) isadded to the handcrafted AR file for playback along with the visualaspects of the handcrafted AR overlays. The number of audio optionconsidered prior to receiving an audio selection or the time spentadjusting the audio selection may be recorded and designated proof ofeffort data.

FIG. 13A depicts a GUI presented on a display. The GUI depicts acustomized AR primary object 608 including a first customization 1300(in the form of a cat image added to a t-shirt and a secondcustomization 1302 (in the form of a hand drawn image). The GUIadditionally includes a series of selectable indicators, including amusic indicator 1304, for use in further customizing the AR primaryobject 608. Selection of the music indicator 1304 results in display ofthe GUI presented in FIG. 13B for selecting a recording for inclusionwith the AR primary object 608. The GUI in FIG. 13B includes a pluralityof recordings list 1306 from which a user may select to customize the ARprimary object 608. In one example, the background 1308 may be blurred(not shown) in order to avoid disclosing sensitive content.
